Furnace Filter
It is Recommended that you replace your Air Handler filter at minimum every 3 months.
Your home has a 20X20X1 filter at the Air Handler.
To replace, remove the middle panel with screwdriver, remove old filter and replace filter and re-install panel.
Above most doors in your unit there are grills that that allow for air return to the utility and laundry rooms. Do not obstruct any of these returns, or there will be air imbalance within your unit.
